Research and Teaching Interests: Ecology, Population Biology, Animal Natural History, Aquatic Environmental Biology

Education:
  • BS, Washington University (St. Louis), Biology
  • PhD, Washington University (St. Louis), Reptile Natural History

My interest in the field and environmental areas of biology have their roots in my childhood growing up in the Ozark foothills of Missouri. Here I played in the creeks and rivers and turned over rocks and logs looking for critters. This led to me desiring to pursue an academic and research career where I could continue and expand my early interests. I have now been at UAB for 40+ years and have taught Introductory Biology, Natural History of the Vertebrates, Ecology, Environmental Biology, and Biology Study Away courses. My research interests have focused on the natural history of various reptiles, amphibians, and fish, with particular emphasis on human impacts on these species.

I was Chair of the Department of Biology from 2000-2008 and have served on a number of Boards of Directors of local and state environmental organizations, including Forever Wild of Alabama. I have also served as President of the Alabama Fisheries Association, the Alabama Academy of Science, and the Association of Southeastern Biologists.

Research in my laboratory has centered around two major areas: animal natural history and aquatic environmental biology. These studies are approached from both the field and laboratory perspective.

Natural history studies on selected animals generally emphasize reproductive cycles, life history strategies, and population dynamics. Several species of reptiles, amphibians, fish, and marine invertebrates have been objects of study. Many of these investigations have been performed to provide basic biological and population information on potentially endangered species or those of possible economic importance.

Studies on aquatic environmental biology involve interaction with other faculty members. Water quality evaluations by both chemical and biological means are performed. Assessments of fish and benthic invertebrate communities are made by seasonal sampling. Of special interest is the use of biological organisms as indicators of the health status of aquatic ecosystems. Recent studies have investigated the effects of increasing urbanization on the Cahaba River and the possible effects of the Gulf oil spill on coastal marsh keystone species.
